Explicit Messaging Services

Overview

Every explicit message performs a service. Each service is associated with a service code. Identify the explicit messaging service by its name, decimal number, or hexadecimal number.

You can execute explicit messages using the DATA_EXCH function block in the Control Expert .

DTM

(device type manager) A DTM is a device driver running on the host PC. It provides a unified structure for accessing device parameters, configuring and operating the devices, and troubleshooting devices. DTMs can range from a simple graphical user interface (GUI) for setting device parameters to a highly sophisticated application capable of performing complex real-time calculations for diagnosis and maintenance purposes. In the context of a DTM, a device can be a communications module or a remote device on the network.
